Witzenmann's flexible metallic elements and pipe brackets are used in many power generation plants. Our products ensure security and optimal operation not only in conventional power plants (coal, gas, oil), in nuclear power plants, in stationary large engines but also increasingly in wind and solar power plants (CSP).
For conventional power plants, our standard product range includes flexible pipeline elements and our pipe support range. In the maintenance field with the rapidly available warehouse range.
Our expansion joints, valve bellows and flexible metal hoses are used in research plants such as CERN, DESY, ITER or also the Wendelstein fusion stellarator. And in conventional nuclear plants.
More than 40 inspections during the production process, a multitude of tests before, during and after production, checks during the processes by customers and certification companies ensure production is monitored to the highest degree possible. Starting with material tests and ranging as far as special film packaging for the flexible pipeline elements.
Depending on their use, cogeneration units are operated as combustion engines, gas engines, gas turbines or fuel cells. Based on the principle of power-heat coupling, they are used where power or heat are needed.
As with large engines, e.g. for ships, we ensure long-term functional safety here in liquid closed loops, exhaust gas sytems before and after the turbo charger or in charged air pipes.
In parabolic trough and fresnel power plants, solar rays are concentrated in a receiving tube via a mirror. This consists of a coated steel tube that transports a heat-bearing medium and a vacuum-insulated glass tube. Metal bellows are needed at each end of a receiver section to absorb heat expansions and maintain the vacuum between the tubes.
Mirrors and receivers in parabolic trough power plants track the sun, the receivers expanding as they are heated. High pressure metal hoses are used as a flexible connection to the fixed tubing of a power plant.
In modern wind power systems, flexible metallic pipeline elements are used to compensate for vibrations, torsional movements and to transport media.
For example, flexible metal hoses in hydraulic oil and coolant circuits, or as heat exchangers, to cool power generators.
Utmost reliability, comprehensive documentation
Our expansion joints, valve bellows and flexible metal hoses are used in research plants such as CERN, DESY, ITER or also the Wendelstein fusion stellarator. And in conventional nuclear plants or when power plants are being dismantled.

Iter Vacuum Handbook
From 1.4571 via magnifier, mu-metal to high-alloy stainless steels - with our broad experience and certified welding approvals, we have a wide range of possibilities for using the right material in each case along with appropriate processes.
More than 40 inspections during the production process, a multitude of tests before, during and after production, checks during the processes by customers and certification companies ensure production is monitored to the highest degree possible. Starting with material tests and ranging as far as special film packaging of the flexible pipeline elements.
Every individual product process must be documented and remain viewable for 30 years. This quickly reaches 5000 pages. A measure to secure the overall system later.
Alongside the process technology, documentation is one of the biggest challenges in nuclear engineering.
In the nuclear field, especially, it is important to be able to model a matching product range. This reduces safety risks and enhances operating efficiency.
